Interim head coach Tony Sparano is an exception to that rule. He signed a contract through 2015 to remain the team’s offensive line coach. If he is not hired as the head coach, Sparano is not expected to remain on staff. The Raiders would release him from his contract in that scenario, and he could find employment as an offensive line coach or an offensive coordinator with another team.

The rest, however, are free to go.

The Raiders are at the tail end of a search to find their next head coach and, if someone other than Sparano is hired, most assistants from Allen’s staff were expected to be let go anyway.

Assistant secondary coach Marcus Robertson is someone to keep an eye on. He received rave reviews working primarily with the safeties this year. Brandian Ross made marked improvement. So did soon-to-be free agent Charles Woodson, who said his chance of returning would increase with Robertson on staff.

Defensive line coach Terrell Williams saw the handwriting on the wall and has already accepted an identical post with the University of Florida.

Quarterbacks coach John DeFilippo will reportedly interview to be the Cleveland Browns offensive coordinator on Friday. The Browns also requested permission to interview senior offensive assistant Al Saunders, though it’s uncertain whether a talk has been scheduled.
